Take a good look at the new Xiaomi YI 2 4K Action Camera II International version in English for the United States.
The new Xiaomi Yi 2 4K Action Camera is an updated version of the original Yi 1. It now uses the Ambarella A9 chipset similar to the GoPro Hero 4 Black edition, and has a 2.19-inch, 330 ppi resolution touchscreen display built in and is comparable to the GoPro Hero 4 Silver. It also offers a 2-pack, 1,400 mAh battery to top the GoPro Hero 4, and can record 110 minutes long of 4K video at 30 frames per second. The Xiaomi Yi 2 can also support 1080p (up to 120fps) and 720p (up to 240fps) for super slow-mo video recording. The battery life can now hit a max of up to 8 hours on standby and 2 hours of continuous video shooting with 4K.
The Xiaomi Yi 2 2.19-inch LCD display on the back is a big plus and step up. Coming with Corning Gorilla Glass protection, it is reported to be running on a resolution of 640*360 along with 330ppi pixel density and 160 degrees viewing angle. Sweet!
